The subject of carbon dioxide emissions is hardly a simple one, especially when it comes to electric cars. They may not have tailpipes, but the electricity generated in order to keep them going has to come from somewhere.

The subject of carbon dioxide emissions is hardly a simple one, especially when it comes to electric cars. They may not have tailpipes, but the electricity generated in order to keep them going has to come from somewhere. Electric utilities, it turns out, are doing their bit to reduce carbon emissions—and that makes it even more important... 
Last month, U.S. Energy Secretary Rick Perry signed an agreement with Saudi Arabian officials to research "carbon capture" technology for fossil fuels, the Department of Energy announced. Perry and Khalid Al Falih, the Saudi Minister of Energy, Industry, and Mineral Resources, signed a memorandum of understanding to "establish a framework for... ![ExxonMobil oil refinery, Baton Rouge, Louisiana, by WClarke [CC BY-SA 4.0]](https://images.hgmsites.net/tmb/exxonmobil-oil-refinery-baton-rouge-louisiana-by-wclarke-cc-by-sa-4-0_100641388_t.gif)
One of the world's largest oil producers is about to enter a tit-for-tat battle over climate change with government officials from multiple states. New York, Massachusetts, New York City, and a slew of cities in California have brought multiple lawsuits against oil producers for a lack of disclosure of potential liabilities they may face. Those... 
Mother Nature doesn't pay attention to politics. As a pair of articles in The Washington Post last week highlighted, climate change proceeds apace regardless of the daily news cycle. In other words, unless the U.S. and the world ramp up the pace of reducing carbon-dioxide emissions from all sources, the effects of a warming planet will continue... 
As nations, automakers, and utilities contemplate how to tackle climate change in real terms, a perfect storm of competition is brewing that will—ideally—produce positive change for the rest of us. Automakers and electric utilities have been incentivized to build electric vehicles and install vast numbers of public charging stations to... 
One year ago at the Detroit auto show, a company called Achates Power unveiled models of a new kind of internal-combustion engine. With opposed pistons in the middle and crankshafts at either end, it was sufficiently different to startle most visitors who paid attention. That engine came with some audacious claims, too: How about an EPA combined... 
It's been hanging out there in limbo for more than six months: the answer to the question of what happens to gas-mileage rules under Trump. Given the daily political turmoil emanating from Washington, D.C., the fate of corporate average fuel economy rules may have gotten lost in the noise. But for automakers and consumers, the fate of current CAFE... 
It remains entirely unclear if the world as a whole will be able to cut its emissions of carbon dioxide fast enough to keep the global temperature rise below 2 degrees C over the next few decades. That's the level at which scientists say the most dire effects of climate change may be lessened or averted. Recent news has been both positive and... 
As children, we're all taught to turn off the lights behind us as we leave an empty room. But it seems Norwegians have taken that lesson one step further. Along a 5.5-mile stretch of road in Hole, Norway, smart streetlights automatically dim when nobody's around—then come back to full power when a car, pedestrian, or other object approaches... 
Ten years ago, energy security may have been as much a driving force behind electric cars for U.S. policymakers as climate change. Now, with continuous growth in domestic oil and gas production over that period, you just don't hear energy security discussed as much. Scientists agree that the effects of manmade climate change, on the other hand...
